Persona Dental Data Breach Impacts 3,386 Patients

Persona Dental, a family dental practice in Sartell, Minnesota, disclosed a data breach that affected 3,386 individuals in the United States.

A ransomware group known as INC Ransom claimed responsibility for the attack on Persona Dental. On June 6, 2026, the group posted on the dark web, claiming to have obtained data belonging to the dental practice.

Because the breach was reported through the federal health data breach notification system, it involved protected health information. However, the specific types of protected health information or personally identifiable information compromised in this incident have not been detailed in available public records.

The exact timeline of the attack, including when it started, how long the hackers had access to the practice's systems and when the breach was first discovered, has also not been made public.

The breach was disclosed to the U.S. Department of Health and Human Services on Sept. 10, 2026.
